: Cutaneous immune-related adverse events occur in more than one-third of patients treated with immune checkpoint inhibitors; they are often the first clinical manifestation although they may occur months after initiation of therapy.We noticed that our patients usually have these cutaneous adverse events on photodamaged skin. In fact, out of 19 patients being treated for metastatic melanoma, patients (42%) with significant cutaneous actinic damage presented cutaneous immuno-related adverse events earlier and in a more serious form. Thus, our metastatic melanoma patients with photodamaged skin who were initiating immunotherapy were given a high oral dose of nicotinamide (500 mg twice daily)for the entire duration of therapy. In treated patients, the appearance of the first signs of cutaneous immuno-related adverse events was 180 days after starting therapy rather than 65 days for untreated patients.

Abstract
: Cutaneous immune-related adverse events occur in more than one-third of patients treated with immune checkpoint inhibitors; they are often the first clinical manifestation although they may occur months after initiation of therapy.We noticed that our patients usually have these cutaneous adverse events on photodamaged skin. In fact, out of 19 patients being treated for metastatic melanoma, patients (42%) with significant cutaneous actinic damage presented cutaneous immuno-related adverse events earlier and in a more serious form. Thus, our metastatic melanoma patients with photodamaged skin who were initiating immunotherapy were given a high oral dose of nicotinamide (500 mg twice daily)for the entire duration of therapy. In treated patients, the appearance of the first signs of cutaneous immuno-related adverse events was 180 days after starting therapy rather than 65 days for untreated patients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
